I had shut my homebrew CNCrouter down for about a yearand recently fired it up again. Using the same PC, mouse, keyboard, programs etc. However I cn no longer use my up and down keys to move the around the table. I am sure I am missing something, but can find no instructions on the computer or in Mach3 that references the UP/Down arrows (buttons) or configurations.
Any ideas will help and be appreciated.
Thanks PeterJ
